The controller 460 may control the user interface 440 based on a result sensed by at least one sensor 430. For example, after counting the number of puffs using a puff detection sensor, when the current puff number reaches a preset number, the controller 460 gives the user an aerosol generating device ( 400) will be ended soon.

In one embodiment, the preset number of puffs may be a number of times that is subtracted by a predetermined number from the maximum number of puffs at which the heater 420 is terminated. For example, when the maximum number of puffs is set to 10, the control unit 460 counts the number of puffs using a puff detection sensor, and when the current number of puffs reaches 9, the control unit 460 uses a lamp, a motor, and a speaker. At least one of them may be used to notify the user that the aerosol generating device 400 is about to be terminated.

In addition, the controller 460 may count the number of puffs using a puff detection sensor, and then terminate the operation of the heater 420 when the current puff number reaches the maximum number of puffs. For example, when the current number of puffs reaches the maximum number of puffs, the controller 460 may set the mode of the aerosol generating device 400 to a sleep mode.

Meanwhile, although not shown in FIG. 4, the aerosol generating device 400 may constitute an aerosol generating system together with a separate cradle. For example, the cradle may be used to charge the battery 410 of the aerosol generating device 400. For example, the aerosol generating device 400 may charge the battery 410 of the aerosol generating device 400 by receiving power from a battery of the cradle while being accommodated in an accommodation space inside the cradle.

5 is a view for explaining an example of a power profile and a temperature profile in a preheating mode according to an embodiment.

The aerosol-generating device includes a heater that heats an aerosol-generating material, a battery that supplies power to the heater, and a controller that controls the overall operation of the aerosol-generating device.

Referring to FIG. 5, a first graph 51 represents a preheat mode temperature profile, and a second graph 52 represents a preheat mode power profile. Specifically, the first graph 51 represents the heating temperature of the aerosol-generating material over time, and the second graph 52 represents the power supplied to the heater over time. Alternatively, the first graph 51 may represent the heating temperature of the heater over time, and the second graph 52 may represent the power output from the battery over time.

Hereinafter, it is assumed that the first graph 51 represents the heating temperature of the aerosol-generating material over time, and the second graph 52 represents the power supplied to the heater over time.

The controller may set the mode of the aerosol generating device to the preheating mode 510 in response to an input signal for starting the operation of the heater.

In an embodiment, the position change detection sensor of the aerosol generating device may detect a position change of a slider that is movably coupled to the body of the aerosol generating device. When the slider moves from the first position to the second position, the controller may receive an input signal from the position change detection sensor and set the mode of the aerosol generating device to the preheating mode 510. The first position may be a position in which the slider covers the end of the mouthpiece as shown in FIG. 2, and the second position may be a position in which the slider exposes the end of the mouthpiece to the outside, as shown in FIG. The first position and the second position are not limited thereto.

Referring to FIG. 5, an input signal for starting the operation of the heater is generated at a first time 501, and the controller may set the mode of the aerosol generating device to the preheating mode 510 in response to the input signal.

In the first graph 51, T1 may be a room temperature, T2 may be a heating temperature of the aerosol-generating material at the second time 511 when the preheating mode 510 ends, and T3 may be a temperature at which an aerosol is generated from the aerosol-generating material. . From a point in time when the temperature of the liquid composition contained in the cartridge of the aerosol generating device exceeds T3, the liquid composition may be vaporized to generate an aerosol. Meanwhile, T3 may vary depending on the type of liquid composition. For example, T3 may be 100°C and T2 may be 80°C, but is not limited thereto.

In the second graph 52, W1 may be a small amount of power. For example, the control unit may apply a small amount of power to the heater to measure the temperature using the heater before the operation of the heater is started, or to check whether the cartridge is coupled. Alternatively, W1 may be a power level, that is, 0W in a state in which power supplied to the heater is cut off.

The controller may control power supplied to the heater so that the aerosol is not generated from the aerosol-generating material in the preheating mode 510.

In an embodiment, the control unit may set the preheat mode power profile in consideration of the holding time of the preheat mode 510. For example, as shown in the second graph 52, the controller may control the power output from the battery so that a constant power level W2 is supplied to the heater in the preheating mode 510. That is, even if a constant power level W2 is supplied to the heater from the first time 501 to the second time 511 during which the preheating mode 510 is maintained, an aerosol is generated at the second time 511 when the preheating mode 510 ends. The heating temperature of the material is below T3. For example, W2 may be 0.8W, but is not limited thereto.

Meanwhile, the power value of the preheat mode power profile may be kept constant as shown in FIG. 5 or may change over time.

The controller may receive a puff detection signal from the puff detection sensor and terminate the preheating mode 510 in response to the puff detection signal. Referring to FIG. 5, a puff detection signal is generated at a second time 511, and the controller may terminate the preheating mode 510 in response to the puff detection signal. In an embodiment, the controller may switch the preheating mode 510 to the heating mode in response to the puff detection signal. The heating mode will be described later in FIG. 6.

As the power supplied to the heater is controlled so that the aerosol is not generated from the aerosol-generating material in the preheating mode 510, the battery life can be extended by reducing the power consumption, and the aerosol condensation before the user puff prevents leakage of liquid. can do.

6 is a diagram for describing an example of a power profile and a temperature profile in a plurality of modes according to an exemplary embodiment.

Referring to FIG. 6, a first graph 61 represents a temperature profile, and a second graph 62 represents a power profile. Specifically, the first graph 61 represents the heating temperature of the aerosol-generating material over time, and the second graph 52 represents the power supplied to the heater over time. Alternatively, the first graph 61 may represent the heating temperature of the heater over time, and the second graph 62 may represent the power output from the battery over time.

Hereinafter, it is assumed that the first graph 61 represents the heating temperature of the aerosol-generating material over time, and the second graph 62 represents the power supplied to the heater over time.

The controller may set the mode of the aerosol generating device to the preheating mode 610 in response to an input signal for initiating the operation of the heater. The controller may control power supplied to the heater according to the preheat mode power profile so that the aerosol is not generated from the aerosol-generating material in the preheat mode 610.

In the first graph 61, T1 may be a room temperature, T2 may be a heating temperature of the aerosol-generating material at the second time 611 when the preheating mode 610 ends, and T3 may be a temperature at which an aerosol is generated from the aerosol-generating material. . In T4 and T5, an aerosol is generated from an aerosol-generating material, and the amount of aerosol generated may increase as the temperature increases.

In the preheating mode 610, a preheating mode temperature profile may be set so that the temperature of the aerosol-generating material becomes T3 or less. For example, in the preheating mode 610, the controller may control the power output from the battery so that a constant power level W2 is supplied to the heater.

The control unit may receive a puff detection signal from the puff detection sensor, and in response to the puff detection signal, change the mode of the aerosol generating device from the preheating mode 610 to the heating mode 620.

In the heating mode 620, the controller may control power supplied to the heater according to the heating mode power profile so that the aerosol-generating material is heated to the target temperature. In the heating mode 620, the heating temperature is kept constant, thereby providing a constant amount of aerosol to the user.

In one embodiment, the heating mode 620 may be divided into a plurality of divisions, and in the heating mode 620, a power level for each of the plurality of sections may be set so that the aerosol-generating material is heated to a target temperature.

For example, as shown in the second graph 62, the heating mode 620 can be divided into four sections, and in the four sections, the heating temperature of the aerosol-generating material can be maintained at the target temperature T4. have. However, since the first section is immediately after the transition from the preheating mode 610 to the heating mode 620, the heating temperature of the aerosol-generating material may increase until the heating temperature of the aerosol-generating material reaches the target temperature T4. .

In addition, as shown in the first graph 61, the heating mode 620 may be divided into four sections, and a power level for each of the four sections can be set. The power level supplied to the heater in the heating mode 620 may be higher than the power level in the preheating mode 610.

The controller may supply W31 to the heater in the first section, W32 to the heater in the second section, W33 to the heater in the third section, and W34 to the heater in the fourth section. The power levels W31, W32, W33, and W34 corresponding to each of the four sections may gradually decrease over time. For example, the power levels W31, W32, W33, and W34 supplied to the heater in each section of the heating mode 620 may be 5W, 4W, 3W, and 2W, respectively.

Meanwhile, the number of sections included in the heating mode 620 is not limited thereto. In addition, the power level corresponding to each section included in the heating mode 620 may be kept constant for each section as shown in FIG. 6, or may change over time even within each section.

The control unit may measure a time when the aerosol generating device has been operated in the heating mode 620. When the time when the aerosol generating device operates in the heating mode 620 exceeds a preset time, the control unit may switch the mode of the aerosol generating device from the heating mode 620 to the idle mode 630. In addition, the controller may measure the progress time for each section of the heating mode 620.

For example, the aerosol generating device may be set to operate in the heating mode 620 for 2 seconds. In addition, each of the four sections shown in FIG. 6 may be set to proceed by 0.5 seconds.

Referring to FIG. 6, the controller may switch the mode of the aerosol generating device from the heating mode 620 to the idle mode 630 at a third time 621. That is, when the aerosol generating device is operated in the heating mode 620 from the second time 611 to the third time 621, the control unit sets a preset time when the aerosol generating device operates in the heating mode 620. It is determined that it has passed, and the mode of the aerosol generating device may be switched from the heating mode 620 to the idle mode 630 at the third time 621.

The controller may control power supplied to the heater based on the idle mode power profile. In one embodiment, the control unit may control the power supplied to the heater based on the idle mode power profile so that the temperature at which the aerosol-generating material is heated in the idle mode 630 is below the target temperature of the heating mode 620 . In addition, the controller may control power supplied to the heater based on the idle mode power profile so that the temperature at which the aerosol-generating material is heated in the idle mode 630 is equal to or higher than the temperature at which the aerosol is generated from the aerosol-generating material.

Referring to FIG. 6, the temperature at which the aerosol-generating material is heated in the idle mode 630 is included in the range of the target temperature T4 of the heating mode 620 and the temperature T3 at which the aerosol is generated from the aerosol material. You can control the power supplied.

As the heating temperature of the aerosol-generating material increases, the amount of aerosol generated increases. The idle mode 630 is a non-puff state in which the user does not puff. If the aerosol-generating material is heated to the same temperature as the heating mode 620 even in the idle mode 630, when the user resumes the puff (i.e. 4 hours (631) of the aerosol may be oversupplied to the user. To prevent this, the temperature at which the aerosol-generating material is heated in the idle mode 630 may be set to be less than or equal to the target temperature of the heating mode 620.

In addition, when the aerosol is not generated from the aerosol-generating material in the idle mode 630, the aerosol supplied to the user may be insufficient when the user resumes the puff again (ie, the fourth time 631). To prevent this, the temperature at which the aerosol-generating material is heated in the idle mode 630 may be set to be higher than the temperature at which the aerosol is generated from the aerosol material.

The power level supplied to the heater in the idle mode 630 may be constant. Alternatively, the power supplied to the heater in the idle mode 630 may change over time. For example, the control unit may supply the heater with a power level W2 equal to the power level supplied to the heater in the preheating mode 610.

The controller may receive a puff detection signal from the puff detection sensor and terminate the idle mode 630 in response to the puff detection signal. Referring to FIG. 6, a puff detection signal is generated at a fourth time 631, and the control unit may terminate the idle mode 630 in response to the puff detection signal. In an embodiment, the controller may switch the idle mode 630 to the heating mode in response to the puff detection signal.

On the other hand, as the heating temperature of the aerosol-generating material increases, the amount of aerosol generated increases. The idle mode 630 is a non-puff state in which the user does not puff, and if power is supplied to the heater at the same power level as the heating mode 620 even in the idle mode 630, when the user resumes the puff again (i.e., The aerosol may be oversupplied to the user in the fourth time (631). To prevent this, the power level supplied to the heater in the idle mode 630 may be set lower than the power level in the heating mode 620.

In addition, when the aerosol is not generated from the aerosol-generating material in the idle mode 630, the aerosol supplied to the user may be insufficient when the user resumes the puff again (ie, the fourth time 631). To prevent this, the power level supplied to the heater in the idle mode 630 may be set to be higher than the power level of the preheating mode 610.

The control unit may measure a time when the aerosol generating device has been operated in the idle mode 630. When the time when the aerosol generating device operates in the idle mode 630 exceeds a preset time, the control unit may switch the mode of the aerosol generating device from the idle mode 630 to the sleep mode. In the sleep mode, a small amount of power may be supplied to the heater or the power supply may be cut off.

In addition, when the time when the aerosol generating device operates in the sleep mode exceeds a preset time, the aerosol generating device may be turned off. For example, when the aerosol generating device is turned off, power supplied to hardware components other than the position change detection sensor may be cut off.

For example, if the aerosol generating device operates in the idle mode 630 for more than 1 minute, the control unit may switch the mode of the aerosol generating device from the idle mode 630 to the sleep mode. In addition, when the time when the aerosol generating device is operated in the idle mode 630 exceeds 2 minutes, the aerosol generating device may be turned off.

7 is a diagram for describing an example of counting the number of puffs according to an exemplary embodiment.

The aerosol generating device includes a puff detection sensor, and the puff detection sensor may detect a user's puff based on any one of a temperature change, a flow change, a voltage change, and a pressure change. The control unit may count the number of puffs using a puff detection sensor.

The control unit may measure the time the aerosol generating device has been operated in the heating mode. When the time when the aerosol generating device operates in the heating mode exceeds a preset time, the control unit may switch the mode of the aerosol generating device from the heating mode to the idle mode.

In addition, the control unit may receive a puff detection signal from the puff detection sensor and switch the mode of the aerosol generating device from the idle mode to the heating mode in response to the puff detection signal.

Referring to FIG. 7, when the mode of the aerosol generating device is changed from the idle mode to the heating mode based on the puff detection signal, the controller may count the number of puffs. The control unit may cut off the power supplied to the heater when the number of puffs reaches the maximum number.

After counting the number of puffs based on the puff detection signal, the controller may notify the user that the aerosol generating device is about to end using at least one of a lamp, a motor, and a speaker when the number of puffs reaches a preset number. . In an embodiment, the preset number of puffs may be a number of times subtracted by a predetermined number from the maximum number of puffs at which the heater is terminated.

For example, the maximum number of puffs of the aerosol generating device may be set to n times. In this case, after counting the number of puffs based on the puff detection signal, the controller may cut off the power supplied to the heater when the number of puffs reaches n times.

In addition, the control unit may count the number of puffs based on the puff detection signal, and when the number of puffs reaches n-1, it may notify the user that the aerosol generating device is about to be terminated.

8 is a flowchart illustrating a method of controlling an aerosol generating device according to an exemplary embodiment.

Referring to FIG. 8, in operation 810, the aerosol generating apparatus may receive an input signal for initiating an operation of a heater.

The aerosol generating device may include a heater that heats an aerosol-generating material, a battery that supplies power to the heater, and a control unit. In addition, the aerosol generating apparatus may include a main body, a slider coupled to the main body so as to be movable, and a position change detection sensor that detects a position change of the slider.

In an embodiment, the position change detection sensor may detect a position change of a slider that is movably coupled to the main body. When the slider moves from the first position to the second position, the controller may receive an input signal from the position change detection sensor.

For example, the first position is a position in which the slider covers the end of the mouthpiece as shown in FIG. 2, and the second position is a position in which the slider exposes the end of the mouthpiece to the outside as shown in FIG. I can.

In addition, the aerosol-generating device may include a cartridge that accommodates the aerosol-generating material and is detachably mounted to the body. After the cartridge is mounted on the main body, the controller may receive an input signal from a position change detection sensor.

In step 820, the aerosol generating device may set the mode to the preheating mode in response to the input signal.

In an embodiment, the controller may set the mode of the aerosol generating device to the preheating mode in response to an input signal received from the position change detection sensor.

Alternatively, after the cartridge is mounted on the main body, the controller may set the mode of the aerosol generating device to the preheating mode in response to an input signal received from the position change detection sensor. That is, when it is determined that the cartridge is not mounted on the main body, the mode of the aerosol generating device may not be set to the preheating mode even if the control unit receives an input signal from the position change detection sensor.

The controller may control the power supplied to the heater according to the preheat mode power profile so that the aerosol is not generated from the aerosol-generating material in the preheat mode. As the power supplied to the heater is controlled so that the aerosol is not generated from the aerosol-generating material in the preheating mode, the battery life can be extended by reducing the power consumption, and the aerosol condensation before the user puff can prevent leakage of liquid. .
